Description
If the IndexTool or IndexScrutiny tool run with the snapshot option and the timestamp is before the hbase.regionserver.optionalcacheflushinterval then they should skip flushing as whatever is in the memstore will not be read by the scanners and takes extra overhead.
Additionally both of these jobs should cleanup their snapshots after they complete or this will take up dfs capacity unnecessarily.
